ALFRED BELLARD, or ram -FRANCE;

" i-mascara ATTACHMENT non MACHINE-GUNS.

To all whom it may concern:

Be it known that I, ALFRED BELLABD, a citizen of the Republic of France, residing in Paris, France, have invented certain new and useful Improvements in Periscopic Attachments for Machine-Guns, of which the following is a specification.

This invention consists of improvements in or relating to periscopic or hyposcopic attachments for machine guns.

The system of the present invention consists in substance in a box made in two parts hinged together, in which the handle, butt or other part of the machine gun is inclosed; this box being held closed by a cam lever or eccentric lever or clamp-ing device serving for fixing the apparatus to the gun.

The two hinged parts of the box may each comprise the recesses necessary for receiving or seating the handle, butt or other part of the machine gun, which recesses may vary according to the shape of the handle, butt or part to be inclosed, or the recess may be formed in only one part of the box, the other part forming in a sense a cover.

The accompanying drawings show tw practical forms of the invention.

Figure 1 is a side elevation of the complete system capable of application to a machine gun having a handle or butt.

Fig. 2 is a front elevation thereof.

Fig. 3 is a horizontal section on line a b, Fig. 1.

Fig. 4 is a horizontal section of a detail of construction.

Fig. 5 is a side elevation of a modification of the box for inclosing the butt of a machine gun.

Fig. 6 is a front elevation thereof.

In Figs. 1 to 3 the connecting device between the machine gun butt and the hyposcope is constituted by a box in two parts 1 and 2, connected together bya hinge 3 at top. In this construction, the parts 1 and 2 of the box are both formed with a groove 4 of channel form for inclosing the butt of the machine gun between them when the two parts 1 and 2 are held together, this belng effected by operating a clamplng cam lever 5. When this lever is turned down it carrles Specification-otLetters Patent.

with it a bar 6 pivoted at 7 on the part 1 of the box, and thereby allows of opening 1tohe box for the insertion of the machine gun utt.

In the form shown in Figs. 5 and 6, only the part 1 of the box is recessed at 4 to receive the butt of the machine gun, the part 2 then simply forming a cover.

The eriscope formed of two tubes 8 and 9 sliding one in the other, is carried by the connecting device or box by means of a slideway 10 carried by the box and a sliding piece 11 fixed to the periscope. Conversely with notches and working in a guide 13 fixed.

to the tube 9, the upper part of which rod is connected to a stud 14 carrying a pointer 15 moving over a scale. This stud 14 which is fixed to the upper tube 8, slides in a slot 16 of the lower tube 9. I

The upper tube is held in the desired position of adjustment by means of a spring de tent pin 17 adapted to engage in that notch of the rod 12 which is opposite to it in the adjusted position.

Claims:

1. Periscopic apparatus for fixing to machine guns, comprising a box in two parts hinged together, in which the handle, butt or other part of the machine gun is imprisoned; means for holding or clamping the two parts of the box together; the box hav other part of the machine gun; a cam lever for clamping the two parts of the box together; an attaching device carried at the rear of the box, and a periscope adapted to be fixed in said attaching device.

3. Periscopic apparatus for fixing to machine guns, comprising a box intWo parts hinged together, having a recess or seat of givenshape. to receive the handle, 'butt or other part of the machine gun; means for clamping the tWo parts of the box together; a periscope adapted to be fixed to the box, and adjusting means for the eriscope, comprising a notched rod and a spring clamp engaging the notches therein. 10

In Witness whereof, I have hereunto signed my name. in thepresence of a subscribing Witness.
